Create and review technical materials for external audiences, including security blogs, white papers, presentations, and other technical content. Collaborate with engineering and R&D teams to develop innovative product features and capabilities within the security domain. Maintain a strong awareness of evolving cybersecurity threats, technologies, standards, and best practices. Requirements: Advanced knowledge of applied cryptography, including technologies such as Hardware Security Modules (HSMs) and Trusted Platform Modules (TPMs). Strong understanding of the complete key management lifecycle, including key generation, storage, distribution, backup, rotation, revocation, and destruction. Deep expertise in web and browser security technologies, including the Same-Origin Policy, XSS, CSRF, HTTP security headers, browser architecture, and JavaScript engine internals. Thorough understanding of networking and operating-system fundamentals, including TCP, HTTP, TLS, DNS, firewalls, WAFs, discretionary and mandatory access controls, and sandboxing. Strong AWS security experience, including IAM, AWS Organizations, EC2, VPC, and related cloud security capabilities. Familiarity with static and dynamic application analysis concepts, methodologies, and tools. Advanced proficiency in C/C++, particularly secure coding practices, along with strong experience in at least one additional programming language, preferably Python or JavaScript. Demonstrated ability to investigate complex technical security problems hands-on and take ownership of finding practical solutions. Strong architectural thinking and the ability to evaluate security implications across products, infrastructure, integrations, and emerging technologies. Excellent communication skills and the ability to explain complex security concepts to engineering teams, customers, executives, compliance teams, and other non-specialist audiences. Ability to collaborate effectively across technical and business functions and contribute to high-impact security decisions. Master's degree in computer science, engineering, cybersecurity, or a related discipline, or equivalent experience; a PhD is preferred. A proactive, ownership-oriented approach with a willingness to work hands-on when required to solve challenging security problems.
